Mr. Tom Halpin:

Part of the PV pilot that we are supporting for homes will consider how to use technology to make better use of PV when it is available. Separately, the building regulations will shortly be subject to revision and the concept of near-zero energy buildings will formally be introduced as part of the energy performance of buildings directive. Under its principle of cost optimality, a full cost-benefit analysis is done of what is the best technology to bring a building to virtually zero energy use and zero carbon emissions. Depending on a building's use, it results in certain prioritisations. This applies not just to schools, but to all commercial buildings. The prioritisation will decide the best mix of technologies and how to make buildings more efficient.

More so than other technologies, it is relatively easy to retrofit buildings with PV panels if the business case improves, but it is not always the case that it is commercially sensible to invest in PV for schools. No different than any other large property owner, the Department of Education and Skills has to make decisions about how to use its budget sensibly.
